14 Dell Virtual Remote Desktop Solution Reference Architecture

Building Blocks for Medium Configurations

The components of Medium Configurations are:

•

Servers:

The configuration utilizes 1U/2U rack servers. 1U rack servers

have low local storage capacity, so they work well with Provisioning Server.

If local storage is used, a 2U or larger server is preferred. Network

connections on XenServer servers use both of the embedded NICs—

typically one for the virtual machines and the other for storage and

infrastructure connections.

•

CPU:

Quad core CPUs are recommended in all XenDesktop solutions for

maximum virtual desktop scalability.

•

Memory:

The 16 GB RAM provides enough memory to deploy 32 384M

virtual machines per XenServer.

•

Network:

The two onboard and one add-in DualPort gigabit NICs provide

enough bandwidth to support VM image streaming and network traffic,

while leaving the remaining PCI-e slot(s) available for additional
